Overview of Hub

Management

Hubs themselves are rarely the cause of problems on the network.

However, since hubs are the center point for many devices on the

network, it’s a good place to start looking for problems.

There are four categories of management tasks:

• Configuring the hub or stack of hubs. This includes setting the IP

configuration, naming the hubs, and disabling individual ports.

• Monitoring traffic. This helps to plan network expansion or make

segmenting decisions.

• Finding malfunctioning devices such as LAN adapters in PCs.

• Finding wiring problems between an attached device and the hub.

There are several methods for managing hubs. You can use any

combination.

• Manage with the onboard LCD or Console Manager. This method

works best for initial setup or when the network goes down and

you can’t access the hub with an SNMP application.

• Manage with Intel Device View for Web or LANDesk® Network

Manager. These SNMP applications are tailored for Intel products

and show a graphical representation of the hub.

• Manage with any other SNMP-compliant application. If you

already use an SNMP application, you can manage hubs by

compiling the hub’s MIB files into that application. File locations

are listed on page 51.

Managing multiple hubs

To manage multiple hubs, you must stack them using Intel Cascade

Cables.

Hub numbering

Once connected with Intel Cascade Cables, the Management Module

numbers hubs from top to bottom, regardless of the placement of the

Management Module.

Collision domain assignments

All hubs running at the same speed in the stack belong to the same

collision domain. In the example below, all devices (PCs, print

servers, and so on) connected to hubs 1 and 2 share 100 Mbps of

bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of

bandwidth.
